SIP 199 Early Dialog Terminated vs 414 Request-URI Too Long
SIP 199 (Early Dialog Terminated) is a 1xx Provisional response, while 414 (Request-URI Too Long) is a 4xx Client Failure response. 199 indicates that a UAS can send this to indicate that an early dialog has been terminated. Used when forking results in multiple early dialogs. In contrast, 414 means that the server is refusing to service the request because the Request-URI is longer than the server is willing to interpret.
